My friend and I were just talking about this same thing a couple of nights ago. We used to go to the mall and walk around all night, back in jr high and the first couple of years in high school. It was the big thing to do where we live.
We went the other night to do some shopping and get her nails done and there were freakin teenagers EVERYWHERE. The whole night we were cussing them under our breath everywhere we went. At one point she said, "You know this officially makes us old, right?"
The thought had already occurred to me earlier but I didn't wanna say anything, lol.
